108 Principles of TRIZ

24 problem Standard contradiction

(+)-factor (-)-factor

The bicycle is heavy and bulky, it is diffi-cult to carry and store

Ease of transportation and storage

Large weight and overall dimensions

Time: 1978

Solution: continued development of fold-ing bicycles in Germany

TRIZ: Segmentation, Dynamization, Lo-cal property, Copying

Time: 2008 Solution: the Contortionist model is a surprisingly simple realization of the Matryoshka principle – the entire con-struction is hidden between the wheels, and the folded bicycle is easy to roll!

TRIZ: Segmentation, Dynamization, Lo-cal property, Copying, Inverse action, Transition into another dimension, Matryoshka Time: 2008 Solution: a graduate of the Royal College of Arts (RCA, London) designed some-thing which is "apparently incredible" – a collapsible wheel!

TRIZ: Segmentation, Dynamization Time: 2009

Solution: Mexican designer Victor Ale-man proposed a bicycle where all com-ponents are disassembled into small parts and then turned into a "nested doll"!

The bicycle is bulky, it is difficult to car-ry and store

Ease of transportation and storage

Large size

Time: 2008 Solution: smaller wheels, radical modifi-cation of the traditional frame form

TRIZ: Segmentation, Dynamization, Lo-cal property, Copying, Inverse action, Transition into another dimension, Matryoshka Time: 2008 Solution: further reduction of wheel size (the wheels are now almost as small as those of a scooter) + the Genius model is fitted with an electric motor

TRIZ: Segmentation, Dynamization, Lo-cal property, Copying, Inverse action, Replacement of mechanical matter Time: 2009

Solution: this Grasshopper also shatters our familiar perceptions of design and functionality, So – to paraphrase a famous maxim – the bicycle is as inexhaustible as … the atom!

The chain is the most "obsolescent" sys-tem component of the bicycle!

It is necessary to im-prove gear efficiency

Transmission has too many links

Time: 1869 Solution: invention which can only be described as a stroke of genius! Who knows, maybe the future of the bicycle is its "well forgotten" past?! – see below

TRIZ: ideal (in a fashion) TRIZ-Solution: the system is reduced to its op-erating element! + Copying, Inverse ac-tion, Local property, Matryoshka Time: 2008

Solution: history repeats itself at a new level of evolution! This model does have a chain – although it is quite small!

TRIZ: ideal TRIZ-Solution: transmission is considerably reduced! + Copying, Lo-cal property, Matryoshka

Time: 2008

Solution: this one has no chain, either! The wheels of this "bicycle" are joined by a flexible transformer frame which can assume bizarre shapes

TRIZ: Inverse action (very radical!), Lo-cal property, Dynamization – and simple sense of humor!

When going uphill, it is difficult to push the pedals even in low gears; people with weak health find it difficult to ride the bi-cycle for a long time

Negotiate steep hills; increase duration of the trip

There are no suita-ble gears; muscle power is insuffi-cient

Time: since the 1990-es

Solution: invention of electric bicycles with storage batteries and electric motors

TRIZ: Replacement of mechanical mat-ter, Separation, Local property, Copying, Partial or excess effect, Discard and re-newal of parts, Mediator, Unite

Time: 2009

Solution: the motor-wheel is designed by Carlo Ratti's MIT SENSEable City Lab

TRIZ: trend – idealization and reduc-tion!

Time: 2009

Solution: reduce! One of the authors was apparently inca-pable of letting go of one "redundant" wheel. Well, at least the others did not stand on ceremony – and this is what we have as a result. I do not even know what to call these machines – light motorcycles or su-per-heavy bicycles… As for the pedals, well, you cannot push them because they are not there. To compensate for that, there are plenty gyroscopes and a powerful electronic brain…

Use of composite materials makes the bi-cycle lighter – and more expensive

Weight of the move-able object

Complex construction consisting of many components

Time: 2008

Solution: in its laconic expression, this extraordinary idea is similar to the origi-nal marginal concept of a "bicycle" as a "wheel with pedals"!

TRIZ: Reduction + Inverse action, Matryoshka

Time: 2009

Solution: Australian inventor Michael Jenkins invented another "foot-wheel" concept (basically, a scooter)

TRIZ: Reduction + Segmentation, Sepa-ration, Dynamization, Inverse action, Lo-cal property, Copying

Time: 2009 Solution: you can stand, and you can sit! Is this a bicycle, or is this a scooter?... Be that as it may, Dean Kamen's Segway has robbed many people of their sleep! And, naturally, there is a massive infor-mational resource represented by multiple gyroscopes and processors – so that you don't even have to think!

TRIZ: reduction – to the operating ele-ments, to the "last" wheel (well, it IS a dual wheel)! Time: 2008 Solution: a "tow car"! If you complete this scooter with a saddle, it will turn into a "bike" – with the pedals cut off…

TRIZ: Segmentation, Separation, Local property, Inverse action, Transition into another dimension, Mediator (!), Matry-oshka

29 problem Standard contradiction (+)-factor (-)-factor

Modern bicycles are heavy and have poor power-to-weight ratios

Increase of storage bat-tery capacity

Large weight

Time: 2006 Solution: and this is just a joke, not a bike but a scooter! But in this case we can say that it is a "re-duced" Comte de Sivrac bike! If only it had an electric motor!

TRIZ: reduction – to the operating ele-ments, to the "last" wheel! Time: since the 1990-es

Solution: and this is a wonderful "hobby horse" of Trevor Blackwell, a very seri-ous engineer and entrepreneur from the Silicon Valley. Only the pedals are mis-sing!

TRIZ: almost total reduction if the pro-totype is a real bike, or expansion if the prototype is a monocycle!

Time: 2009 Solution: invention of an "almost" mon-ocyclic bike with an electric drive – what a beauty! Animations are especially im-pressive!

TRIZ: Trend – partial reduction to one operating wheel! Time: 2008 Solution: something evocative of a "ka-mikaze in a torpedo" – this invention draws a lot of attention and causes bitter arguments

TRIZ: Reduction + Inverse action, Tran-sition into another dimension + fantasy. My teacher Stanislaw Antonovich Baltsevich used to say: "There is no limit to both human fantasy and human stupidity!" He than went on to provide a suitable quote from the great Ein-stein. (NB: the second part of my teacher's statement does not apply to this example.)

Look, standing is bad, sitting is good, and lying is even better, that's why we have recumbent models! What else would you want?! So our idea is siple – look at the alternatives and… do what you think is best!



(+)-factor (-)-factor It IS TRUE – it is difficult to learn to ride the bicycle, and it is equally difficult to ride it using just one wheel…

Comfort, safety Unreliability, in-stability

Time: 2009 Solution: This bike manufactured by Gy-robike, a company established by gradu-ates of the Dartmouth College, USA, in-creases stability of the bicycle – which is quite useful when you are teaching your kid to ride it!

TRIZ: Replacement of mechanical mat-ter, Separation, Copying, Matryoshka Time: 2009

Solution: Due to inbuilt gyroscopes, this bike/scooter can stand "by itself", while the ingenious construction of its wheel endows it with an ability to move in "all directions"!

TRIZ: Reduction! + Segmentation, Self-servicing, Feedback, Universality

Time: since the 1990-es Solution: Inventor Thomas Gordon sees such robots exploring the Mars and the Moon. It rolls BY ITSELF (apparently obeying TRIZ laws). But will it be able to stand up BY ITSELF if it falls? TRIZ: Replacement of mechan. matter, Separation, Local property, Copying


(+)-factor (-)-factor Bicycle ergonomics, efficiency and de-sign will continue to improve. How?

Comfort, safety, ease of use

Weight, dimensions

Time: 2009 Solution: design-concept of this hybrid was suggested by a 1992 Olympic cham-pion (there is little left to add: miniature storage battery and electric motor + pedal gear)

TRIZ: trend – idealization!

Finally, to prove that the bicycle is as inexhaustible as the atom, I will give you several examples of more obscure ideas which have not gained such pop-ularity. However, these examples have considerable cognitive and esthetic value, and to leave them out of this book would mean to detract from the knowledge and impressions of my re-spectable readers.

I am not commenting on these exam-ples. Instead, I exhort you (if you like them, that is) to use them to hone your extracting and reinventing skills.

Also, I would like to draw your atten-tion to the fact that some of these illus-trations can be classified as belonging to steampunk*, a branch of fantastic and visual arts which I believe is im-bued with nostalgia for lost genera-tions producing numerous engineering and social failures. Naturally, not all of these things would have been found useful, and not all of them are likeable. Still, they all leave a lot of room for the imagination…

Main problem – do not fall asleep!

Pity you cannot make it any longer – it will be too difficult to turn!

All according to TRIZ: if you

cannot make it longer, make it

rounder
